element presenting the appearance of. one or more bricks or other building units, the individual units being represented as separated by the mortar bond in the usual manner.

The structure of my units is novel'and they lend themselves to the close simulation of a wall built of bricks or the like.

I also provide a new and improved element for building up the corner of thewall or the joint of a wall opening.

I also provide a new and improved element for forming the arch or top of a window or door opening in the. Wall.

I also provide new and improved means for ventilating the rear of a wall surface formed of my improved elements, thereby obviating the collection of dampness andthe occurrence of rot.

Other novel and advantageous features will appear from the following description. In the accompanying drawings, which however are not intended to limit the scope of my invention to what is therein shown 7 but merely to illustrate the best embodiment of the principles of my invention now known to me, Fig. 1 is a broken elevation showing a plurality of the individual typeof my sidlng elements secured to a vertical wall and assembled in overlapping relation; Fi .2 is a sectional view taken along the II-II in Fig.1; Fig. 3 is a perspective of one of said elements; Fig. 4 is a reduced section taken along the line IVIV in Fig. 3;

Fig. 5 is an edge view showing two elements assembled in overlapping relation and embodying modification; Fig. 6 is a plan view of another modified form of the individual element; Fig. 7 is a semen taken along the line VIIVII in Fig. 6; Fig. 8 is an edge view vshowin two of said elements in overlapping relatlon; Fig. 9 is an elevation showing theelement developed in the fbrm of a horizontally extended strip designed for. the simulation of a plurality of bI'ICkS OI inc 4 other building units; Fig. 10 is a perspective of one of the corner elements, and Fig. 11 1s a perspective of one of the elements for forming the top of a window or door opening.

Referring first to Figs. 1 to 4, inclusive, 1 represents the wall or other substantially vertlcal support to which the siding is to be applied. The siding elements are indicated in general by the numeral 2, and in Fig. 1 three of said elements, 2*, 2 and 2 are shown attached to the wall 1, the unit 2 being below and the units 2 and 2 overlapping the same from above and breakingjoints therewith.

Referring to Fig. 3, it is seen that the body'of the element is in the form of a relatively thin back plate 3 which is pref-- erably rectangular in form and is provided.

on its lower portion with an outwardly protruding block portion 4 which is shaped and colore or other building unit. I have shown the representation as that of a horizontally disposed brick but it will be understood that the same may be of a brick laid on end or otherwise disposed.

and formed to represent the brick As shown in Figs. 2 and 3 the plane of n the front face or surface of the block portion 4 is not arallel with the general" plane of the backing plate 3 but diverges upwardly therefrom; this divergence compensating for the upwardly and inwardly inclined angle which the element assumes when placed in position on thewall iIioverlapping relation with the element'below. Thus when in lace on the wall the front surface of the block portion 4 is substantiall vertical. The top and bottom surfaces 0 the block portion 4 are in planes at substantiall right angles to the front surface thereo so as to be substantially horizontal when the element-is in place.

When, as in Figs. 1 and 3, my element is of the individual type with a single block portion thereon, such block portion preferably. extends flush with one of the vertical edges of the backing plate, as shown at the left in Figs. 1 and 3, while at its other end said block portion is stepped back from the edge of the backing sheet, leaving a narrow I sunken strip 5 which is of the width us'ufil suchasbricks, commonly a half inch. The surface of the strip 5 is in a. plane substantially parallel with'the plane of the as the'mortar bond between building the plane of the top surface of the block I form the portion 4.

The inner vertical edge of the strip 5 meets the end surface of the block portion 4 with a slight curve or fillet 7 and the outer vertical edge of the strip 5is provided with a similar fillet 8. It is evident that the end of the block portion 4 of the next element will abut against the strip 5, the strip thus separtin the two block portions in simulation of t e mortar bond. The fillets 7 and '8 increase the resemblance to pointed mortar which usually meets the bricks with a curve.

In the figures of the drawings now belng described, the lower edge of the backing plate 3 extends below the block portion 4 forming asunken strip 9 which is horizontally disposed and is of substantially the same width as the vertical strip 5. The strip 9 meets the lower surface of the block portion 4 with a curved fillet 10 and its lower edge is provided with a curved fillet 11 which bears against the top surface of the block portion 4 of the elements next below when in position. The plane of the front surface of the strip 9 is substantially parallel with that of the front surface of the block portion 4 and when the elements are as sembled in overlapping relation,the lower edge of theelement above bears on the top surfaces of the block portions 4 and on the shoulders 6 of the elements below, the surface of the strip 5 below merging at its top into\the surface of the strip 9 of the element above, the strip 9 being colored and formed like the strip 5 to represent mortar bond.

In Fig. 5 the lower edge of the strip 9 is not provided with the fillet 11 but the top surface of the block portion 4 is provided with a concaved bead 11 behind which the lower edge of the element above fits as shown;

In Figs. 6, 7 and 8 I show the block 4 extending down flush with the lower edge of the'backing plate 3, the horizontal mortar bond being represented b the strip 9 above the block portion 4, t e up er side of the'strip bein defined by the llet 10 against which the ottom edgeof the element a ove rests, as shown in Fig.- 8. In this upper end of the strip 5 merges into the strip 9 This last described form of element is particularly advantageous where the, element is formed b other materials w ile; in a plastic state. I

For the purpose of providing ventilation molding of cement and and preventing the accumulation of dampness and the occurrence of rot, the top edge of each of the elements is provided with one or more notches 12, preferably of arcuate shape, into which merge the upper ends of the flutings 13 formed in the rear surface of the backing plate 3, said flutings extending down sufliciently to partially overlap the notches 12 of the elements next below, and

the flutings and notches are so located that continuous vertical air spaces are thus formed in the rear of the elements. The flutings are preferably of upwardly increasing depth.

14 represent nail holes through the backing plates 3, the same being placed just below the lower ends of the flutings 13 so that the nails intersect the notches 12 of the elements next below. Thus the nails pass through but one element, reducing by onehalf the number of nail holes required.

In Fig. 9 I have shown a unit 2 wherein the backing is formed as a horizontally ex: tended strip 3, and the front lower face of the same provided with a horizontally disposed series of any desired number of block portions 4*, 4", 4, 4, etc. One end block portion, such as 4, extending flush with the adjacent edge of the backing whilethe other end block portion such as 4 is shown spaced inwardly fromthe adjacent edge of the backing with a strip .5 interposed between the same, and the block portions being separated by strips 5, similar in character to the strip 5, but merging at either side with the block ortions in the manner already described in connection with the strip 5. Each of said strips 5 and 5 end in a vertical shoulder 6 similar to that alreadydescribed in connection with the strip 5. The block portions 4, 4 4 and 4 are stepped upwardly from the lower edge of the backing 3 to provide the stri 9 as already described in connection with't e preceding figures.

The strip elements 2* are assembled in overlapping and staggered relation so that the horizontal rows of block portions will break joints with those above and below and the lower ed e of the upper stripbears on the top of t e block portions of -the lower strip.

For use in forming the corner or end of the wall I provide the corner element 2 shown in Fig. 10, the backing plate 3 being angular in horizontal cross sectional, form as is also the block portion 4, the side of the brick .being represented on one face 'o'f the element and the end of the brick on the other face thereof. The corner block illustrated is a right-hand block and it. will be understood that left-hand blocks, with the representation of the brick reversed,- are furnished s'o that" I by their alternate use the broken joints of the brick work may be simulated.

In Fig. 11 I show the strip element 2 which I provide for the top of a window or door opening, the lower end of the block portions 4 being turned in horizontally as at P to represent the lower ends of the brick or building units which form the arch.

15 represents the upwardly tapered spacer member which is introduced between the lower element or row of elements and the wall 1 to give the proper inclination to the same. A large number of materials are adapted for use in the manufacture of my elements. Thus the backing plate may be of flexible material,such as flexible asbestos board or other waterproof material, while the block portions 4 are preferablypf more rigid material, such as cement or similar material fixed to the backing board. Again the entire elemeL. may be made of a suitable cementitious material forming a rigid or substantially rigid element. For this purpose I may use an artificial slate or asbestos compound.

It is evident from the foregoing that my improved siding material may be quickly and permanently attached to the wall and that it will closely simulate walls of brick. stone and the like. It is also evident that the siding is durable and likewise inexpensive.

In some of the views of the drawings I have shown the block portions which represent bricks and the like simulating bricks horizontally disposed and in some cases bricks vertically disposed. It is understood that the bricks may be simulated as disposed either horizontally or vertically in connection with any of the forms of my element which I have illustrated.
